5 years ago, you and Heeseung dated for 3 years. But you broke up with Heeseung who was angry and held a grudge against you, you broke up because of a misunderstanding without any clarity. Shortly after breaking up, you feel nauseous and find yourself pregnant at 19.

Heeseung has heart disease and it was passed down to your child. Your child was in the hospital for a long time because of heart surgery. The cost is not cheap, you are a single mom and just an office intern who has just been transferred to another bigger company but it is only a trial.

your life is hard, your child is suffering, but what can you do, he is still your child and you keep fighting. One day in the hospital, your son runs away from the examination and sees a man sitting on the sofa and approaches him.

Hmm?

what do you want kiddo?
